ICE-CREAM DISHER.

Specification. of Letters Patent.

Patented Sept. 1, 1914.

Application filed September 26, 1907. Serial No. 394,728.

To ('71 '717107Jb it may concern 'i it known that I, RAYMOND B- GIL- rur s'r. a citizen of the United States, residing: at Newark, in the county of Essex and how Jersey, ha e invented certain n w and uset'ul improvements in Ice-Cream it ers, o'l which the lie-(ion.

The invention relates to ice cream dishand more particularly to that type {lenliy known as automatic dishers, which adapted to he held and operated to discharge the cream therefrom by one hand.

Hue object of the invention is to provide a disher, which so organized, that its parts may he readily taken apart and assembled and which will be thoroughly sanitary in its construction.

llthcr objects of the parent from the device scribed.

The invention consists of the several novel features hereinafter set forth, and more particularly defined by claims at the conclusion invention will he apas hereinafter dehereof.

In the drawings :Figure 1 is a perspective of the assembled disher. Fig. 2 isa detail perspective of the bowl and the, handle which is rigidly secured thereto. Fig. 3 is a perspective of the scraper, and the shaft upon which it is mounted. Fig. 4 is a detail perspective of the lever which is pivoted to the handle. Fig. 5 is a sectional figure showing by full lines the normal position of the actuator arm, and by dotted lines, the position assumed when the lever has been shil'ted to operate the scraper.

The disher comprises a frame 4, which has one of its ends rigidly and permanently attai'rhcd to one side of ,a'hemis nierical howl 1. lhis frame comprises a shank or approximately straight-portion 5 forming, in ellect a part of the handle and an integral handloportion (3, which is laterally offset with respect to the shank 5.

it. scraper comprising a pair of arcuate blades 15, is adapted to sweep across the inner l'acc ot the bowl to sever the ice cream from the howl. This scraper issecured to a. sha 1' 1.7, and is rotatable in the bowl. A trunnion 16 on the outer end of the scraper is adapted to it into a hearing 2 Whichis i'ormed in one side of the bowl. An open hearing 3 is formed at the opposite side of tho howl, and the shaft 17 passes through following is a HD0614 said bearing and is removable transversely through said bearing. .\-le'ver S isprovided wlth a pivot-pin 11 which fits in an opening 9 which evtends through a lug; 7. on frame 1; and a lug, 12 on lever S is adapted to abut against the face of lug 7. The side portion of the lever 8 extends laterally from the pivot 11 so that it will be opposite the laterally oll'set handle (3 andso that the lever may be operated by pressing: the lever 8 and handle (3 together. v The outer end of framed and the outer end of lever El are each extended inwardly, and in each of these inwardly extending portions there is formed an opening 14. The opening 1 in frame is adapted to receive and towns a hearing for a stud of sleeve 21. Said sleeve is slidably connccted to a square portion 22 on the outer end of shaft 17, by a socket in said sleeve which is correspoinlingly square, so that rotation of the sleeve. will impart rotation to the shaft. The slidahle connection between the sleeve 21. and the shaft, 17 permits stud 20 to be. withdrawn from its hearing in the frame-l to permit the scraper and shaft to he removed. .ispring 23 in the socket formed in sleeve 21. and between the sleeve and the outer end of shaft 17 serves to hold the sleeve in operative relation to the frame.

An actuator arm 18 is formed on sleeve 21. and a stud 19 on said arm fits into the hole 1t in lever 8. As shown in Fig. 5, the inner ends of the inward extensions at the outer ends in frame and lover, respectively, are adapted to abut against each other to limit thepivotal movement of the actuatorarm and lover in one direction, and to limit the outward movement of lever 8. A coilspring 13 having its terminal seated in socket-s 12 in the lever and frame respectively, serves to operate and press the. lever 8 outwardly to rotate shaft 17- in one direction and to retract the scraper after it has been operated in the opposite direction by manual force applied to the lever.

in operating the device, assuming arm 18 and shaft 17 to rotate the, scraperv discharge the me cream.

in the bowl and it to be assembled, as shown inFig. 1, the opertherefrom. Upon release of lever 8 spring 123 will retract the scraper, shaft and actuator arm to the normal position shown in full lines in Fig. 5.

When it is desired to clean the device, sleeve 21 may be moved longitudinally of sha ft 17 to withdraw studs 20, 19, from the openings in the frame and lever respectively, and thereupon, shaft 17 may be lifted laterally out of open bearing 3 to remove the scraper from the bowl. Shaft 17 when held in operative position, overlies lug 12* of lever 8 and thus serves to hold the lever in pivotal relation to the frame. lVhen the shaft and sleeve are in operative position, they rotate together and the'sleeve serves as means, which is movable on the shaft, for holding the shaft in operative position by reason of the stud 20 being held in the bear ing 14 on the frame 4. This sleeve, in operation also serves in effect as a shaft-section or member, so that said bearing 14 will indirectly serve as a hearing at or support for the outer end of the shaft 17. The sleeve and shaft constitute separahly or slidably connected elements for permitting rotating the scraper. Furthermore, this sleeve operates in effect as an extension on the shaft which is sustained in a bearing in alinemcnt with the open bearing 3 so that both ends of the shaft will be removably supported in alinement with tho trunnion-bearing 2. By providing means, which is movable on the shaft 17 to release it for removal, the necessity of first or independently removing or releasing the operating lever or the spring for operating the lever, is avoided.

The invention thus exemplifies an ice cream disher, from which the scraper and shaft may be readily and quickly removed. After the scraper and shaft have-been removed, the lever may also be readily dis connected from the frame by liftin stud 11 out of the; opening 9 because withd rawal of stud 19 from opening 14, and removal of the overlying shaft-17 will permit the lever' to be separated from the handle.

The invention is not to be understood to be restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
